You got an 0335 and still having the starting problem since "sorting" the immobiliser issue - as I said earlier Al - "Symptoms now classic crank sensor issues. Think you seem to have cured the immobiliser issue, and anything further to do with the key is a red herring." IMO!
colin , since stripping the key & relocating the "chip" the car has started perfectly with no more "cut outs" as before .
Also the 0335 code was present when I first got the car & first read the codes.
I think I have heard that some codes will self clear after a certain amount of start ups if the problem clears .
I have only started this car about 30 times since I have had it ,so would that 0335 be an old one that had not self cleared ?
I have now had the codes cleared . . so if we get another non start or cut out & the 0335 re appears then it would almost certainly be a faulty crank sensor .
I am hoping that I may get an answer to the question I asked a few posts back, about if the imobiliser barrel sensor would cause the engine to cut out while running if the "chip" moved & lost contact with the sensor if it was loose in the key .
I think I will post just that question again in a new thread & see if i get any response
thanks
